Target: Minister of Environment and Forestry, Indonesia
Goal: Protect critically endangered Tapanuli orangutans by implementing an immediate moratorium on destructive land-use activities in their habitat.
Extreme rainfall and devastating landslides, intensified by human-caused climate change, have killed a staggering 7% of the world’s rarest great ape, the Tapanuli orangutan, raising urgent alarms about the species’ survival. A recent study details that 58 of the remaining 800 individuals were lost after nearly 40 inches of rain fell within just four days, equating to an 11% reduction in the local population. This tragic event underscores the alarming consequences of climate change and habitat destruction on critically endangered species.
The Batang Toru ecosystem, home to these vulnerable orangutans, has already been significantly degraded by mining, palm oil plantations, and hydropower developments. Over 8,300 hectares of vital habitat were lost to landslides due to extreme weather events. Experts warn that the loss of even 1% of this already precarious population each year may hasten the species’ extinction. The Indonesian authorities have temporarily paused industrial activities in the region, yet immediate action is needed to ensure the survival of this unique ape and its habitat.
Preserving the Tapanuli orangutan population and their ecosystem is essential not only for the survival of this species but also for maintaining biodiversity. An immediate moratorium on harmful land-use activities is necessary to shield the remaining habitat while ensuring effective measures are taken to stabilize the orangutan population.
PETITION LETTER:
Dear Minister of Environment and Forestry,
Recent events have cast a glaring light on the plight of the Tapanuli orangutans, which constitute the rarest great ape species in the world. With an alarming 58 individuals lost to a single climate-induced landslide event, this population is now drastically diminished, raising urgent concerns for their continued existence. The intense and unprecedented rainfall in November 2025, exacerbated by climate change, has resulted in devastating demographic impacts that require immediate intervention.
As scientists have highlighted, this critical habitat, already under threat from mining and agricultural expansion, suffered the loss of over 8,300 hectares due to landslides. Human activities have already pushed these remarkable creatures to the brink, and without decisive action, the first modern extinction of a great ape species could soon become a grim reality. The temporary pause of industrial activities in the Batang Toru area is a much-needed step, but it must be followed by a comprehensive and enforceable moratorium on land-use practices that jeopardize the already fragile Tapanuli orangutan habitat.
We call on you to take immediate action to implement the necessary protections that will ensure the survival of the Tapanuli orangutans. This is not only a moral obligation but a commitment to preserving biodiversity for future generations. Your leadership is crucial in securing the future for this endangered species.
Sincerely,
[Your Name Here]
